Related Posts Widget for Blogger with Thumbnails

Displaying the links to related posts along with a thumbnail of the corresponding post will help you increase the page views/user .Users will be tempted to go for the related posts when they are presented attractively with thumbnails.
This is another first release from me.This one also uses the media thumbnails generated by blogger for each post.
For displaying the thumbnails,this widget will use the images uploaded for the post using the blogger image uploader(from the post editor) [Update - Now supports external images also.]

3.Now Find

<b:if cond='data:label.isLast != &quot;true&quot;'>
</b:if>
<script expr:src='&quot;/feeds/posts/summary/-/&quot; + data:label.name + &quot;?alt=json-in-script&amp;callback=related_results_labels_thumbs&amp;max-results=6&quot;' type='text/javascript'/></b:loop>
<script type='text/javascript'>
removeRelatedDuplicates_thumbs();
printRelatedLabels_thumbs(&quot;<data:post.url/>&quot;);
</script>
</div><div style='clear:both'/>
<!-- remove --></b:if> 
<b:if cond='data:blog.url == data:blog.homepageUrl'><b:if cond='data:post.isFirstPost'>

4.You can adjust the maximum number of related posts being displayed by editing this line in the code.

var maxresults=5;

you will also have to edit the posts per label(it should ideally be one more that maxresults)

max-results=6

5.To edit the title of the widget you can change this line of code

var relatedpoststitle="Related Posts";

6.To change the default thumbnail, you can edit this line of code

var defaultnoimage="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjloPW0eVHpf93xJGMwDTJYRXFcZ8U1sRXCXck3Uh5gsbM8VBCerk7uxCH1ycnfHxlCrKq483B5N7WaMwOm4qpHQIB828XbMAGx3_Dp18zh64xWsC68wHERnCoCo5dxGG6P5q5OR1WNYVw/s400/noimage.png";

If you fall into troubles implementing this,don't panic.. :) .just leave me a comment here and i will help you out. If you like to give me any suggestions on how to improve this widget,then it would be really great.

How to display the related posts on every page and not only on the post pages?

Just remove the two lines starting with <!-- remove --> from both step 3 and step 2.
that is lines

<!-- remove --><b:if cond='data:blog.pageType == &quot;item&quot;'> 

and

<!-- remove --></b:if>

Update 29/03/2012 : If the script is not working for you then please change http://blogergadgets.googlecode.com/files/related-posts-with-thumbnails-for-blogger-pro.js to http://bloggergadgets.googlecode.com/files/related_posts_with_thumbnails_min.js
Sorry for the trouble :-)
